A hybrid intumescent fire retardant coating from cake- and eggshell-type IFRC

In this study the applicability of flame retardant mixed with a carbon source (such as pentaerythritol) for the intumescent fire retardant coating (IFRC) daubed on the top of a piece of plywood was investigated. There are three kinds of flame retardants used in this study: (1) artificial mesophase graphite powder (MGP), (2) sericite (Al₄(OH)₄(KAlSi₃O₁₀)₂), and (3) graphite. The desirable sizes of graphite, MGP and sericite were obtained by sieving. The graphite, MGP and sericite were characterized using a scanning electron microscope (SEM) and an energy dispersive spectrum (EDS). The IFRC, which consisted of 19.8% of flame retardant (or flame retardant mixed with carbon source), 15% of dehydrate agent, 18% of foaming agent, 7.2% of resin binder, and 40% of solvent, was prepared and daubed on the top of plywood. The fire protection capability of IFRC was tested using a flammability 45° tester. A conventional IFRC (with the carbon source) was also prepared to study the effect of adding the mixture of flame retardant and carbon source on the fire protection capability of IFRC. The microstructures of the conventional IFRC, the IFRC with flame retardant, and the hybrid IFRC (with flame retardant and carbon source) were inferred and demonstrated using SEM micrographs of the cross-section of three kinds of burnt IFRC. Most interestingly, the fire protection capability of the hybrid IFRC exceeds that of the conventional IFRC even though the percentage of carbon in the burnt hybrid IFRC is less than that in the burnt conventional IFRC.

Synergistic smoke suppression effect of epoxy cross-linked structure and ferrocene on epoxy-based intumescent flame-retardant coating

The smoke production behaviour of epoxy film former and the synergistic smoke suppression effect of epoxy cross-linked structure and ferrocene (FC) on epoxy-based intumescent flame-retardant (IFR-EP) coating have been investigated. The results show that the cross-linked structure of epoxy/polyamide resin can not only effectively enhance thermal stability and suppress smoke in the early combustion stage, but also reduce the production of toxic and flammable gases and promote the production of non-flammable gases. On the other hand, the FC can suppress smoke by radical reactions in the early combustion stage and promote the production of denser residue char. Moreover, the FC can also effectively reduce the total smoke rate in the whole combustion process.     

Effect of boron compounds on fire protection properties of epoxy based intumescent coating

The aim of this study was to investigate the effect of boron compounds on fire protection properties of intumescent coating based on ammonium polyphosphate (APP). Three kinds of boron compounds namely boric acid (BA), zinc borate (ZB) and melamine borate (MB) were used. Total amount of flame retardant additive was kept constant at 30 wt%, and boron compounds were used at three concentrations of 1, 3 and 5 wt%. Thermogravimetric analysis (TGA), Attenuated total reflectance–Fourier transform infrared spectroscopy (ATR‐FTIR) and fire test were conducted for the determining the fire performance of intumescent coating. According to fire test results, BA and MB showed synergistic effect at 1 wt% loading. ZB showed antagonistic effect at all concentrations. Fire protection effect of intumescent coating decreased as the added amount of boron compound increased regardless of boron compound type because of suppression of intumescence.

氧化石墨烯在膨胀型水性防火涂料中阻燃和抑烟作用研究

以水性丙烯酸乳液为成膜物质,钛白粉为颜料,加入不同量氧化石墨烯(GO)纳米粒子作为协效阻燃/抑烟剂配制膨胀型防火涂料,采用大板燃烧法、锥形量热仪和烟密度测试法对其阻燃和抑烟效果进行了研究。结果表明:GO能有效地提高涂料试样的耐燃时间和降低峰值生烟速率(p SPR),当GO添加量为0.025份时(以100份乳液计,下同),试样耐燃时间可以增加59.5%,当添加量为0.125份时试样的p SPR从0.024 m2/s降至0.013 m2/s。结合扫描电镜(SEM)、热重分析(TG)、差热分析(DTA)和红外光谱(FT-IR)等手段对试样炭层的结构形貌进行分析后发现,具有片状结构的氧化石墨烯在涂料受热膨胀过程中会使自身和基体分子链取向,进而在聚合物炭化过程中形成骨架结构增加炭层强度,达到阻燃和抑烟的目的。     

The dynamic flammability and toxicity of magnesium hydroxide filled intumescent fire retardant polypropylene

The flammability properties of an intumescent fire retardant polypropylene added with magnesium hydroxide was discussed in this study. To evaluate the flammability of the material, limit oxygen index, smoke emission, tensile strength, and our exploitation dynamic flammability evaluation system, tests were assessed in experiments. The results showed that the intumescent flame retardant ammonium polyphosphate-filled polypropylene has superior flammability properties but higher carbon oxide (CO) concentration and smoke density. By adding some magnesium hydroxide additives in intumescent fire retarded polypropylene, the smoke density and CO concentration decrease; and the compound also has superior fire properties. It is concluded that intumescent system and magnesium hydroxide additives are effective on improving combustion properties for polypropylene. © 1998 John Wiley & Sons, Inc.
